Broad inferences such as risk of diabetes, blood pressure, cardiovascular disease etc. This allows for recommendation of diet plans etc. The chart allows you to plot the exact difference between the healthy body state and the current state. InferencesĪ variety of inferences can be drawn from the body mass index. It is divided into various sub zones inside the main categories of underweight, normal, overweight and obese. The chart offers a more detailed analysis. The limits of these ranges can vary a little according to the test administrators, race, age, sex etc. BMI value below 18 shows that the subject is underweight a value between 18 and 25 shows that the subject has a normal weight with respect to his or her height a value between 25 to 30 shows that the subject is overweight and a value above 30 classifies the subject as obese. This table or chart gives the range of the BMI values that represent a body type. The inferences that can be drawn from the specific body mass index value is presented in the form of a table or a chart. BMI Calculationsīody mass Index is found directly by dividing the body mass in kgs by the square f height in meter square. For example, athletes with high muscle mass can get high values of BMI, without having any disorders. However, it is to be remembered that there are exceptions to this thumb rule. Thus abnormal values of body mass index are suggestive of the disorder, which allows the appropriate diagnostic tests to be conducted. Low values of body mass index are correlated with eating disorders, chemical imbalances etc. High body mass index values have been directly correlated with higher risk of vascular diseases, diabetes, abnormal blood pressure etc. Diets and exercise plans are recommended by dieticians on the basis of the body mass index value. Body mass index allows medical professionals to broadly classify a person as Underweight, Normal, Overweight or Obese. However, it is very convenient for medical professionals to apply a rule of thumb to the general public. Relevanceīody mass index measures the size of a human body taking into account the height and weight. It is important to keep in mind that BMI is not a diagnostic procedure, but merely a norm. Body mass index can be calculated using a graphic chart or a table. The value of the body mass index gives a very broad idea about the health of a person based on the tissue mass. It was originally created for population study and not an individual medical examination. The body mass index is a rule of thumb devised by a Belgian mathematician and philosopher in the early 19 th century. The standard unit of body mass index is kilograms per square meter. BMI or body mass index is defined as the body weight in kilograms divided by the square of the height of the body in meters.
